Synopsis:
While Robotman and Negative Woman are testing a new plane, Garguax returns to Earth and sends his Plastic Men to abduct Cliff Steele. Robotman is taken aboard Garguax's ship and pitted against a gladiator named Warrior who proceeds to destroy Cliff's metal body piece by piece.

Negative Woman returns home to rally the team. However, Larry Trainor has sent Reactron to attack Valentina and absorb the negative energy she possesses. The Doom Patrol defends their teammate and forces Reactron to return to Trainor in an unstable state. He then explodes.
